Shortwave Radios In Emergencies: Everything You Need To Know
Having the right tools is an excellent way to prepare for emergencies. Contrary to popular belief, having shortwave radio is one of the best ways to stay connected in times of crisis.
From natural disasters such as hurricanes and wildfires to civil unrest and power outages, shortwave radios provide an efficient way to keep tabs on official and unofficial news sources. This explains why most people rely on shortwave radios in emergencies.
Shortwaves are suitable for emergency purposes since they travel much faster. Moreover, their broadcasts can be transmitted over thousands of miles, including across continents. These features make shortwave radios a crucial tool that never misses in many preppers’ arsenal.
In this article, I’ll talk about the use of shortwave radios in emergencies. I’ll also discuss the pros and cons of these radios and where to buy them. Tune in to know why shortwave radios are poised to be essential in emergencies.
What Is a Shortwave Radio?
A shortwave radio is a type of radio that tunes into shortwave frequencies. Shortwave frequency bands range from 3,000 to 30,000 kHz (3-30 MHz). These frequencies suit long-distance communication and can be received even in unfavorable conditions.
Let’s consider the relationship between wavelength and frequency to better understand what shortwave radios are.
Since frequency and wavelength are inversely proportional, smaller frequency bands are associated with longer wavelengths. This means shortwave radios have longer wavelengths, making them suitable for long-distance communication.
Moreover, due to their high power efficiency and efficient antennas, these radios can receive signals from thousands of miles away.
Is a Shortwave Radio Good for Emergency?
A shortwave radio is good for emergency because it’s designed to work in disaster situations. The radio can work during power outages and over long distances which can be challenging for conventional AM and FM radios.
To this point, I know you want to know the qualities that make shortwave radios suitable for emergencies.
Well, imagine this scenario; you are in the middle of a disaster, and the power is out. You don’t have access to a television, radio, or the internet, meaning your phone is also off. How will you listen to the news to know what’s happening or talk to your family and friends in a faraway place?
This is where shortwave radios come in–you can tune into news broadcasts from different parts of the world or communicate with others through these radios. However, what makes these radios suitable for such emergencies?
Shortwave radios are good for emergencies due to the following reasons:
They Can Receive Broadcasts Over Long Distances
Disasters are unexpected occurrences that can strike an extensive area, cutting off communication. In such a situation, the only way to get help is by using long-range communication channels to speak to people or listen to the news. Shortwave radios do exactly that.
As discussed above, it all narrows down to the relationship between wavelength and frequency. According to the Center for Science Education, low-frequency waves have a longer wavelength, making them suitable to broadcast over longer distances.
Moreover, the ionosphere easily reflects shortwaves to the earth’s surface. Thus, you can use them to receive broadcasts from thousands of miles away.
They Are Portable
Most shortwave radios are lightweight and portable, meaning you can carry them with you even when evacuating your home in the face of a disaster. Additionally, these radios come in handy when camping outdoors or hiking in challenging terrain.
The portability also makes them ideal for emergency communication as it allows you to communicate across distances.
They Work on Batteries
Emergencies like hurricanes and floods can leave you without electricity for days. When this happens, your phone and any communication device that relies on power will be useless. Fortunately, shortwave radios can still work in such conditions because they use a battery power source.
You can use battery packs or any 12 volts power source like a car battery to power shortwave radios.
Some shortwave radios also use hand-crank generators for power.
Although some people argue that FM and AM radios can also use batteries, what they don’t know is that radio stations are usually connected to the grid. Therefore, these stations will be off if the power outage is widespread.
How to Use Shortwave Radios
Now that you know what these radios are and how they work, let’s dive into the most crucial part–how to use shortwave radios in emergencies. Here is a step-by-step guide on how to do that:
Step 1: Buy a Good Shortwave Radio
The first step is to have an excellent shortwave radio. As a rule of thumb, it’s advisable to have a shortwave radio in your arsenal as part of your emergency preparedness plan.
Some key factors to consider when buying a shortwave radio include:
- Power source: A radio that supports multiple power sources like battery, solar, or hand-crank generator is ideal for emergency use.
- Weather alert: It’s also essential to get a radio with weather alerts that notify you of any upcoming disasters. A radio with NOAA or a “Public Alert” logo is a good fit.
- Portability: A portable shortwave radio is easy to carry and store when evacuating your home in an emergency.
- Message encoding technology: The Specific Alert Message Encoding (SAME) technology is an ideal option as it filters out emergency messages from other broadcasts.
Alternatively, you can build your own shortwave radio. Check out this article to learn how to build a shortwave radio.

Step 2: Learn How to Operate Your Radio
As with anything else, you must learn how to operate a shortwave radio for efficiency. This can come in handy if you’re using the device in a stressful emergency. The key concepts to learn include:
- Tuning: It involves searching for and finding the station or frequency you want to listen to. It involves inputting the frequency on the radio’s keypad or tuning it up and down. Check out this article for the best shortwave radio stations.
- Using a microphone: You need a microphone to speak to other people through the radio. It involves connecting your microphone to the radio and pushing the transmit button. However, you must have a Federal Communications Commission License to transmit on these radios.
- Frequency and band range setting: This is the range or channel of sound that a radio station transmits its messages on. You can use different bands with these frequencies, as shown in the table below.
- Antenna installation: You need an antenna to broadcast and receive shortwave radio signals. The best way to get more signals is by extending the telescopic antenna on the radio using a wire (watch the video below for a demonstration).

Hand-Crank and Wind-up Shortwave Radios
Like any other radio, shortwave radios need power to operate. Besides the usual power sources like batteries and mains electricity, hand-crank shortwave radios generate power when a user cranks the handle.
By cranking the handle for a duration between half a minute to two minutes, you generate sufficient power to keep the radio on for half an hour to one hour.
On the other hand, wind-up shortwave radios generate power when a user winds a crank. In short, you’re only required to wind a spring mechanism to drive a generator that emits electricity.
